This article, written by JPT Technology Editor Chris Carpenter, contains highlights of paper SPE 197759, “Energy-Saving Challenges and Opportunities in Upstream Operations Using Value Methodology,” by Mohamed Ahmed Soliman, Saudi Aramco, prepared for the 2019 Abu Dhabi International Petroleum Exhibition and Conference, Abu Dhabi, 11-14 November. The paper has not been peer reviewed. The objective of the complete paper is to investigate and analyze energy-saving and process-optimization opportunities in upstream surface facilities, from downhole to the gas/oil separation plants (GOSPs), using a value-methodology approach. Function analysis was used to identify those functions that can be reduced, eliminated, or synergized to minimize GOSP operating and maintenance cost. All successful opportunities were selected on the basis of their minimum operating expenses and capital expenditure (CAPEX) with a value-engineering methodology. Introduction Value methodology has been implemented successfully in new projects to save costs but rarely has been implemented in oil and gas operating facilities to minimize operating costs. The success of value methodology in reducing capital project costs prompted the author to explore its application to operating facilities, specifically toward minimizing operating and maintenance cost. Value methodology is used when value is a concern and requires optimization. Value is defined as the ratio of function to cost. The value-engineering methodology consists of the following six-step process (Fig. 1): Information: Collect, review, and analyze all information about the project or the plant, including the cost. Review and define current project conditions and identify study goals. Function analysis: Define the primary function of the product or project in a simple format. Creativity: Generate the largest number of innovative ideas (brainstorming) without being controlled by standards and best practices. Evaluation: Evaluate the ideas generated from the creativity phase, eliminate impractical ones, and select the most-profitable and -achievable improvement idea. Development: Develop further the selected best ideas from the evaluation phase and estimate the cost. The development phase includes cost/benefit analyses, drawings, implementation steps, and responsibilities. Presentation: Present the selected ideas to decision-makers and stakeholders for final approval. Case Studies Several energy-saving opportunities were analyzed to highlight the need to check continuously the function of each equipment item and process in any operating facility. Many functions were found to be unnecessary. In some cases, these unnecessary functions adversely affected plant operation. The complete paper provides four case studies; this synopsis will highlight three of them.

Value engineering is an appropriate policy for creating and improving value, which reduces unnecessary costs and maintains core functionality. Despite the mentioned benefits, this approach has so far received little attention in the area of supply chain management. Although this approach is highly structured, limitations such as overemphasizing the cost criterion and failure to meet other criteria, utilizing team members’ votes to rank solutions, ignoring inherent uncertainty and ultimately disagreement between value engineering team members have reduced the effectiveness of this approach. The present study aims to provide a coherent framework for utilizing a value engineering approach to supply chain cost management and overcome the aforementioned limitations by utilizing gray multi-criteria decision-making. In this regard, in the first phase, the initial list of improvement solutions is determined, the criteria extracted from the literature are localized using value engineering team members’ opinion. These criteria are weighted using the gray stepwise weight assessment ratio analysis (SWARA-Gray) method. Then, the score of each solution is calculated by the value engineering team based on the list of criteria as a gray number. The scores are aggregated using the gray evaluation based on distance from average solution (EDAS-Gray) method, and the solutions are prioritized. Finally, the application of the proposed framework is investigated in a real case study in a power plant in Iran. The results of the research show that the final rankings of the solutions rarely changed for different methods; so the model used in this study has acceptable stability.

Implementation of Value Engineering (VE) in the construction industry has become a proven technique for cost optimization. This paper presents a review of the implementation of BIM in construction industry. The factors that triggered and hinder the implementation of VE and BIM in the current industry and a case study of the application of VE using BIM for cost optimization of renovation works are also discussed. The project which was used for the case study is the renovation of shop lot units to be used as a student centre where student activities will be placed. 3D models of the project were developed as BIM model that provide strong visualization when creating alternatives for VE processes. The function analysis, risk analysis and life-cycle cost analysis were applied to determine the value index for each developed alternative. It shows that the implementation had successfully reduced the cost by approximately 27% and the value of the project increased after the process.

Adequate provision of affordable human settlements is a huge challenge in South Africa since its independence. This paper investigates the effects of the cost increase of building materials on affordable housing delivery in South Africa. With potential solutions for cost minimisation of building materials, with the aim of achieving affordable housing delivery in South Africa are provided. This study uses a sequential mixed methods approach, wherein surveys were conducted among the construction professionals (project managers, site managers architects, site engineers, quantity surveyors, contractors, building materials suppliers, and government workers) in the construction industry within Cape Town, South Africa, who were considered as the research participants. The qualitative data obtained from the survey exercise were analysed using content analysis, while the quantitative data were analysed using a descriptive statistical technique on SPSS. The findings attained show fluctuation in construction cost and a rise in maintenance cost (caused by poor workmanship) as significant effects in the cost increase of building materials for affordable housing delivery. Adequate application of the recommendations given in this study will minimise the effects of high cost of building materials and enhance affordable housing delivery. Appropriate handling of the findings given in this study will reduce the effects of the high cost of building materials and augment timely delivery of affordable housing and stakeholders’ satisfaction.

This paper analyzes a novel, cost-effective planar waveguide solar concentrator design that is inspired by cellular hexagonal structures in nature with the benefits of facile installation and low operation and maintenance cost. A coupled thermal and optical analysis of solar irradiation through an ideal hexagonal waveguide concentrator integrated with a linear receiver is presented, along with a cost analysis methodology, to establish the upper limit of performance. The techno-economic model, coupled with numerical optimization, is used to determine designs that maximized power density and minimized the cost of heat in the temperature range of 100–250 °C, which constitutes more than half of the industrial process heat demand. Depending on the incident solar irradiation and the application temperature, the cost of heat for the optimal design configuration ranged between 0.1–0.27 $/W and 0.075–0.18 $/W for waveguide made of ZK7 glass and polycarbonate, respectively. A techno-economic analysis showed the potential of the technology to achieve cost as low as 80 $/m2 and 61 $/m2 for waveguide made of ZK7 glass and polycarbonate material, respectively, which is less than half the cost of state-of-the-art parabolic trough concentrators. Overall, the hexagonal waveguide solar concentrator technology shows immense potential for decarbonizing the industrial process heat and thermal desalination sectors.
